DETAILED DESCRIPTION

The solution of the embodiment of the present disclosure is as follows. A keyword is obtained from a text index pool in response to a visiting request for a webpage from a browser; a recommended text information list is obtained from a keyword index pool according to the keyword; the recommended text information list is embedded into the webpage and the webpage is returned to the browser. A user may click the keyword to obtain the recommended text information list as required, thereby the webpage text information is recommended to a user by using the keyword. The information overload is reduced and the efficiency and effectiveness of recommendation of text information is improved without considerable modification of the original webpage.

In the embodiment of the disclosure, the keyword is set as the connection between the user and the webpage text information, a scheme for corresponding text recommending based on the keyword without considerable modification of the original webpage is provided.

Specifically, the keyword, which is referred to as TAG, label, or the like, is generally the mark of the text made by the user or generated by a program automatically. The keyword is a brief description of the main subject of a text and is widely used in text subject extraction, information organizing, and user interest description and the like. For example, every book and movie in www.douban.com has a TAG made by the user. According to the popular website delicious, users are allowed to tag the webpage they collect. At present, mainstream Apps for news, such as ZHIYUE and zaker, each has the function of displaying the keyword that represents the dimension of news. Therefore, connecting the user and the text by appropriate interact approach with the keyword will not only reduce information overload but also describe the interests of the user so as to recommend personalized information.

Particularly, it is provided a method for recommending text information in a an embodiment of the present disclosure as shown in FIG. 1, which includes the following steps S101 to S104.

Step S101 may include receiving, by a server, a visiting request for a webpage from a browser when the webpage is visited by a user through the browser.

When the webpage is visited by the user through the browser, the visiting for the webpage is carried out by sending the visiting request to the server by the browser. The information, such as uniform resource locator (URL), which is also referred to as the address of a webpage), of the webpage to be visited is included in the visiting request.

Step S102 may include obtaining a keyword from a text index pool in response to the visiting request.

Step S103 may include obtaining a recommended text information list from a keyword index pool according to the keyword.

In the present embodiment, the text index pool and the keyword index pool are created beforehand. A relationship between the URL of the recommended webpage text selected from historical webpages of the browser and the corresponding keyword in the recommended webpage text is stored in the text index pool and the keyword index pool.

The text index pool is formed by a Key (a text index key field) and a Value (the value of the text index key field), and for each recommended webpage text, the key (the text index key field) which is the URL of the recommended webpage text and the value (the value of the text index key field) which is the keyword of the recommended webpage text are stored in pair to form the text index pool.

The keyword index pool is formed by the Key (the text index key field) and the Value (the value of the text index key field), and for each recommended webpage text, a key which is the keyword of the recommended webpage text and a value which is the URL of the recommended webpage text are stored in pair to form the keyword index pool.

The corresponding keyword is obtained by the server from a text index pool created beforehand in response to the visiting request when the webpage is visited by the user through the browser; then a predetermined number of URLs of the recommended webpage text is obtained by the server from the keyword index pool created beforehand according to the corresponding keyword; and thus a recommended text information list which consists of the URLs of a plurality of recommended webpage texts is obtained.

Step S104 may include embedding the recommended text information list into the webpage and returning the webpage to the browser for displaying to the user.

The recommended text information list is linked with a keyword at a corresponding position in the webpage and the keyword at the corresponding position is marked.

The way for marking the keyword at the corresponding position includes but not limited to: highlighting the keyword; displaying the keyword in a color that is different from that of the adjacent words; adding a set icon beside the keyword; or underlining the keyword.

The user may click the marked keyword in the webpage to obtain the recommended text information list according to his/her own needs or interests when visiting the marked webpage displayed by the browser so as to browse the recommended text quickly.

Particularly, according to an embodiment, the above step of obtaining a keyword from a text index pool created in response to the visiting request, as shown in FIG. 2, may include the following steps S1021 to S1022.

Step S1021 may include obtaining a uniform resource locator (URL) of the webpage from the visiting request.

Step S1022 may include obtaining the keyword corresponding to the URL of the webpage from the text index pool, if the keyword corresponding to the URL of the webpage is included in the text index pool.

Where, if the keyword corresponding to the URL of the webpage is included in the text index pool, the keyword corresponding to the URL of the webpage is obtained from the text index pool; if the keyword corresponding to the URL of the webpage is not included in the text index pool, the procedure is ended.

According to the above scheme of the present embodiment, a keyword is obtained by a server from a text index pool in response to the visiting request when the webpage is visited by a user through the browser; a recommended text information list is obtained from the text index pool according to the corresponding keyword; the recommended text information list is embedded into the webpage and the webpage is returned to the browser for displaying to the user; and the user may click the keyword to obtain the recommended text information list as required, thereby the keyword is set as the connection between the user and the webpage text information. The information overload is reduced and the efficiency and effectiveness of recommendation of text information is improved without considerable modification of the original webpage, and the requirement of the user for quick viewing the webpage is met. In addition, the online interaction sequence of the responding of the server and the browser to the visiting of the user for the webpage is a real-time interaction which lasts a very short period of time (for instance, less than 10 ms) so as not to affect the display speed of the original webpage.

As shown in FIG. 3, it is provided another method for recommending text information according to an embodiment of the present disclosure. Based on the above embodiment, before the step S101 of receiving, by a server, a visiting request for a webpage from a browser when the webpage is visited by a user through the browser, the method further includes step S100.

Step S100 may include creating the text index pool and the keyword index pool.

The present embodiment is different from the first embodiment in that the present embodiment further includes the scheme of creating the text index pool and the keyword index pool to facilitate the server obtaining the recommended text information list based on the created text index pool and keyword index pool.

Particularly, as shown in FIG. 4, the above step S100, creating the text index pool and the keyword index pool may include the following steps S1001 to S1003.

Step S1001 may include extracting a first keyword from at least one historical webpage of the browser.

According to an embodiment, the step S1001 may include: extracting a main text from the historical webpage of the browser; performing word segmentation on the extracted main text to obtain candidate keywords; counting information of each of the candidate keywords, such as a word frequency and a distribution parameter of each of the candidate keywords, and calculating a weight of each of the candidate keywords; and setting a candidate keyword of which the weight is greater than a predetermined threshold as the first keyword.

The predetermined threshold may be set according to a specific situation.

The formula for calculating the weight of the candidate keyword is W_(keyword)=TF*D, where TF is the word frequency of the candidate keyword, and D is the distribution parameter of the candidate keyword in the text, and has a value between 0 and 1.

FIG. 5 shows an example of extracting a keyword from a historical webpage.

The keywords are “sharp” and “staff reduction” which have a weight of 32.24695 and 22.75728 respectively.

Step S1002 may include sorting the historical webpages of the browser and taking a predetermined number of the historical webpages of the browser with higher ranking as a recommended webpage text.

Commonly a large number of texts (usually hundreds of texts) are related to each keyword and only preferred several texts (e.g. about 5 texts) are recommended to the user. So hundreds of texts should be sorted in a predetermined way and the preferred texts are recommended to the user.

As an embodiment, the number of hits of a text and an updating time of a text are taken as parameters to calculate a text weight of the historical webpage of the browser; and a predetermined number of historical webpages of the browser with a larger weight are set as recommended webpages.

The formula for sorting may be:

${W_{webpage} = \frac{PV}{T - t}},$

where PV is the number of hits, T is the current time, and t is the time when the text is updated. It is known from the above formula that the greater the number of hits, or the shorter a duration between the current time and the time when the text is updated, the higher the ranking it would have.

Step S1003 may include creating the text index pool by taking URLs of the recommended webpages as Keys of the text index pool and taking the first key as a Value of the text index pool; creating the keyword index pool by taking the keyword as a Key of the keyword index pool and taking the URLs of the recommended webpages as Values of the keyword index pool.

According to the above scheme of the present embodiment, the creation of the text index pool and the keyword index pool is achieved. The server may obtain the recommended text information list according to the text index pool and the keyword index pool.

As shown in FIG. 6, it is provided another method for recommending text information according to an embodiment of the present disclosure. Based on the above embodiment, after the step S101, the method further include:

step S105 including sending the recommended information text list embedded in the webpage to the browser for displaying to the user when the marked keyword at the corresponding position is clicked by the user.

The present embodiment is different from the above embodiment in that the user may click the marked keyword in the webpage to obtain the recommended text information list according to his/her own needs or interests.

Particularly, the recommended text information list is embedded into the webpage and sent to the browser for displaying to the user by the server when the marked keyword in the corresponding position has been clicked by the user. The user may click the marked keyword to obtain the corresponding text information for browsing or subscription if the user is interested in the recommended information. Therefore, according to the scheme of recommending text based on the keyword, it is provided effective support to increase click-through rate of the user, optimize reading experience of the user, and describe interests of the user.

The implementation of the scheme of the present embodiment in a QQ browser is described hereinafter.

The webpage returned to the browser after being recommended by the server when the user visits a portal website through the QQ browser is shown in FIG. 7. The “Apple”, which is taken as the keyword for this webpage, is marked and is available for the user to click.

A recommended window which contains a subscription button and the recommended text related to “Apple” as shown in FIG. 8 will pop out after the user has clicked the keyword “Apple” if the user is interested in this topic.

According to the above scheme of the present embodiment, a corresponding keyword is obtained by a server from a text index pool in response to the visiting request when the webpage is visited by a user through the browser; a recommended text information list is obtained from the text index pool according to the corresponding keyword; the recommended text information list is embedded into the webpage and the webpage is returned to the browser for displaying to the user; and the user may click the keyword to obtain the recommended text information list as required, thereby the keyword is set as the connection between the user and the webpage text information. The information overload is reduced and the efficiency and effectiveness of recommendation of text information is improved without considerable modification of the original webpage, and the requirement of the user for quick viewing the webpage is met. In addition, the online interaction sequence of the responding of the server and the browser to the visiting of the user for the webpage is a real-time interaction which lasts a very short period of time (for instance, less than 10 ms) so as not to affect the display speed of the original webpage.

The text index pool is formed by a Key (the text index key field) and a Value (the value of the text index key field), and for each recommended webpage text, the key (the text index key field) which is the URL of the recommended webpage text and the value (the value of the text index key field) which is the keyword of the recommended webpage text are stored in pair to form the text index pool.

The keyword index pool is formed by the Key (the text index key field) and the Value (the value of the text index key field), and for each recommended webpage text, a key which is the keyword of the recommended webpage text and a value which is the URL of the recommended webpage text are stored in pair to form the keyword index pool.

The corresponding keyword is obtained by the server 402 from a text index pool created beforehand in response to the visiting request when the webpage is visited by the user through the browser 401; then a predetermined number of the URLs of the recommended webpage text are obtained by the server from the keyword index pool created beforehand according to the corresponding keyword; the recommended text information list is embedded into the webpage and the webpage is returned to the browser for displaying to the user; thus recommended text information list which consists of the URL of a plurality of recommended webpage texts is obtained.

Then the recommended text information list is linked with a keyword at a corresponding position in the webpage by the server 402 and the keyword at the corresponding position is marked, and the recommended text information list is embedded into the webpage and the webpage is returned to the browser 401. The webpage is displayed to the user by the browser 401.

The way for marking the keyword at the corresponding position includes but not limited to: highlighting the keyword; or displaying the keyword in a color that is different from that of the adjacent words; or adding a set icon beside the keyword; or underlining the keyword.

The user may click the marked keyword in the webpage to obtain the recommended text information list according to his/her own needs or interests when visiting the marked webpage displayed by the browser 401 so as to browse the recommended text quickly.

The server 402 is further configured to create the text index pool and the keyword index pool. The following scheme is adopted for creating the text index pool and the keyword index pool.

Firstly, a keyword is extracted from at least one historical webpage of the browser 401.

According to an embodiment, the step of extracting may include: extracting a main text from a historical webpage of the browser 401; performing word segmentation on the extracted main text to obtain candidate keywords; counting a word frequency and a distribution parameter of each of the candidate keywords and calculating a weight of each of the candidate keywords; and setting a candidate keyword of which the weight is greater than a predetermined threshold as the extracted keyword from the historical webpage of the browser 401.

The predetermined threshold may be set according to a specific situation.

The formula for calculating the weight of the candidate keyword is W_(keyword)=TF*D, where TF is the word frequency of the candidate keyword, and D is the distribution parameter of the candidate keyword in the text, and has a value between 0 and 1.

Then, the historical webpages of the browser 401 in which the extracted keyword is contained are sorted in a predetermined way and a predetermined number of historical webpages of the browser 401 with higher ranking is extracted as a recommended webpage text;

Commonly a large number of texts (usually hundreds of texts) are related to each keyword and only preferred several texts (e.g. about 5 texts) are recommended to the user. So hundreds of texts should be sorted in a predetermined way and the preferred texts are recommended to the user.

As an embodiment, the number of hits of a text and an updating time of a text are taken as parameters to calculate a text weight of the historical webpage of the browser 401; and a predetermined number of historical webpages of the browser 401 with a larger weight are set as recommended webpages.

The formula for sorting may be:

$W_{webpage} = \frac{PV}{T - t}$

where PV is the number of hits, T is the current time, and t is the time when the text is updated. It is known from the above formula that the greater the number of hits, or the shorter a duration between the current time and the time when the text is updated, the higher the ranking it would has.

Finally, for each recommended webpage text, a key which is the URL of the recommended webpage text and a value which is the keyword of the recommended webpage text are stored in pair to form the text index pool, and a key which is the keyword of the recommended webpage text and a value which is the URL of the recommended webpage text are stored in pair to form the keyword index pool.

Thus, according to the above scheme of the present embodiment, the creation of the text index pool and the keyword index pool is achieved. The server 402 may obtain the recommended text information list according to the text index pool and the keyword index pool.

According to the above scheme of the present embodiment, a corresponding keyword is obtained by a server from a text index pool in response to the visiting request when the webpage is visited by the user through the browser; a recommended text information list is obtained from the text index pool according to the corresponding keyword; the recommended text information list is embedded into the webpage and the webpage is returned to the browser for displaying to the user; and the user may click the keyword to obtain the recommended text information list as required, thereby the keyword is set as the connection between the user and the webpage text information. The information overload is reduced and the efficiency and effectiveness of recommendation of text information is improved without considerable modification of the original webpage, and the requirement of the user for quick viewing the webpage is met. In addition, the online interaction sequence of the responding of the server and the browser to the visiting of the user for the webpage is a real-time interaction which lasts a very short period of time (for instance, less than 10 ms) so as not to affect the display speed of the original webpage.

Finally, it should be noted that the term “including”, “comprising” or any other variations herein are intended to cover a non-exclusive inclusion, such that a number of elements including the process, method, article, or apparatus includes not only those elements, but also other elements not expressly listed or for such further including a process, method, article or set.
